我有5个按钮,我需要做不同的事情,但他们没有,我需要知道如何让他们这样做。

这是我的代码;

public class MainMenu implements Screen {

CrazyZombies game;
Stage stage;
TextureAtlas atlas;
Skin skin;
SpriteBatch batch;
Button play, option, quit, custom, store, menu;

public MainMenu(CrazyZombies game) {
    this.game = game;
}

public void create () {
    stage = new Stage();
}

@Override
public void render(float delta) {
    Gdx.gl.glClearColor(0.09f, 0.28f, 0.2f, 1);
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

    stage.act(delta);
    stage.draw();

    batch.begin();
    batch.end();
}

@Override
public void resize(int width, int height) {
    if (stage == null)
        stage = new Stage(width, height, true);
    stage.clear();

    stage.setViewport(854, 480, true);
    stage.getCamera().translate(-stage.getGutterWidth(), -stage.getGutterHeight(), 0);

    Gdx.input.setInputProcessor(stage);

    /**
     * quit Button
     */

    TextButtonStyle styleQuit = new TextButtonStyle();
    styleQuit.up = skin.getDrawable("8layer");
    styleQuit.down = skin.getDrawable("8layer");

    quit = new Button(styleQuit);

    quit.addListener(new InputListener() {
        public boolean touchDown(InputEvent event, float x, float y,
                int pointer, int button) {
            return true;
        }

        public void touchUp(InputEvent event, float x, float y,
                int pointer, int button) {

        }
    });

    /**
     * End quit Button
     */

     /**
      * store Button
      */

    TextButtonStyle styleStore = new TextButtonStyle();
    styleStore.up = skin.getDrawable("9layer");
    styleStore.down = skin.getDrawable("9layer");

    store = new Button(styleStore);

    store.addListener(new InputListener() {
        public boolean touchDown(InputEvent event, float x, float y,
                int pointer, int button) {
            return true;
        }

        public void touchUp(InputEvent event, float x, float y,
                int pointer, int button) {
            game.setScreen(new StoreScreen(game));
        }
    });

    /**
     * End store Button
     */

     /**
      * customs Button
      */

    TextButtonStyle styleCustom = new TextButtonStyle();
    styleCustom.up = skin.getDrawable("10layer");
    styleCustom.down = skin.getDrawable("10layer");

    custom = new Button(styleCustom);

    custom.addListener(new InputListener() {
        public boolean touchDown(InputEvent event, float x, float y,
                int pointer, int button) {
            return true;
        }

        public void touchUp(InputEvent event, float x, float y,
                int pointer, int button) {
            game.setScreen(new CustomScreen(game));
        }
    });

    /**
     * End customs Button
     */

     /**
      * Options Button
      */

    TextButtonStyle styleOptions = new TextButtonStyle();
    styleOptions.up = skin.getDrawable("11layer");
    styleOptions.down = skin.getDrawable("11layer");

    option = new Button(styleOptions);

    option.addListener(new InputListener() {
        public boolean touchDown(InputEvent event, float x, float y,
                int pointer, int button) {
            return true;
        }

        public void touchUp(InputEvent event, float x, float y,
                int pointer, int button) {
            game.setScreen(new OptionScreen(game));
        }
    });

    /**
     * End Options Button
     */

     /**
      * Play Button
      */

    TextButtonStyle stylePlay = new TextButtonStyle();
    stylePlay.up = skin.getDrawable("7layer");
    stylePlay.down = skin.getDrawable("7layer");

    play = new Button(stylePlay);

    play.addListener(new InputListener() {
        public boolean touchDown(InputEvent event, float x, float y,
                int pointer, int button) {
            return true;
        }

        public void touchUp(InputEvent event, float x, float y,
                int pointer, int button) {
            Gdx.app.log(CrazyZombies.LOG, "un-touched");
            game.setScreen(new GameScreen(game));
        }
    });

    /**
     * End Play Button
     */

    /**
     * start Background
     */

    TextButtonStyle styleMenu = new TextButtonStyle();
    styleMenu.up = skin.getDrawable("background");

    menu = new Button(styleMenu);

    /**
     * End Background
     */

    stage.addActor(menu);
    stage.addActor(play);
    stage.addActor(option);
    stage.addActor(store);
    stage.addActor(custom);
    stage.addActor(quit);

}

@Override
public void show() {
    Audio.playMusic(true);
    batch = new SpriteBatch();
    atlas = new TextureAtlas("data/mainmenu/mainmenu.pack");
    skin = new Skin();
    skin.addRegions(atlas);
}

@Override
public void hide() {
    dispose();
}

@Override
public void pause() {

}

@Override
public void resume() {

}

@Override
public void dispose() {
    batch.dispose();
    skin.dispose();
    atlas.dispose();
    stage.dispose();
    Audio.dispose();
}

public void playButton(Button play) {

}
}

所以我的5个按钮已经设置并且有动作和听众,但是现在他们什么也没做,当我单击一个按钮来测试它有效但按钮可以从屏幕上的任何位置点击,所以我认为它是按钮区域的问题,但我不知道如何设置它。

我尝试过.getheight(),. getWidth等,但它仍然是一样的。虽然在我的纹理图集中,所有图像的高度和宽度都是相同的,但是所有图像都可以成为我的问题吗?

实际上它比这更简单。您需要设置按钮的边界。使用按钮的.setBounds(x,y,width,height)方法,它们还没有尺寸。设置边界后,点击区域应该是正确的。

查看Table layout libgdx并使用表格。

答案 1 :(得分:0)

对于第一个问题,即你的按钮没有做任何事情,我认为这是因为事件会传播到所有按钮,可能按照它们添加到按钮的顺序Stage。问题是您的touchDown()方法返回 true 。这意味着传播应该停止,然后不会调用其他actor的touchDown()方法。 你觉得它什么也没做,但实际上它做了一些事情,只是你的touchDown()方法是空的。

对于第二个问题,可能是因为您没有设置演员的大小。
